In research and fabrication of micro flow pool for a self-made SPR sensor array device

in order to achieve high precision and repeatability

flow through each detecting point is required as coincident as possible.Several different flow pool structures are designed and simulated by using Comsol Multiphysics software.At first

inner flow field distribution of common shuttle-shape flow pool is analyzed

and impact of different transition section is analyzed.Based on this simulation

impact of different shapes of flow pools

especially their outlines

on the flow field distribution are also discussed.And then

effect of some microstructures array design on flow field distribution of detecting area.Simulation results show that appropriately extending the length of the transition section will help to improve the stability and uniformity of the flow of fluid.However

the improvement become smaller when the length exceeded a certain value.While effect of different shapes

on flow field of detecting area is not obvious.Microstructure array design can bring some improvement on the homogeneity of the flow field.
